COUPLING FOR CITY RAILROAD-CARS.

Specification of Letters Patent No. 29,142, dated July 17, 1860.

To all whom it may concern:

Be it known that we, GEORGE CoLLYER and A. HAMILTON PATTERSON, both ofthe city and county of Philadelphia, in the State of Pennsylvania, haveinvented a new and Improved Coupling for City Passenger Railway-Cars andfor Carriages; and we do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, in which Figure 1 is a side view: showing the insideparts of the box in dotted lines and showing the positions of theseveral parts when the operation of coupling is efiected; Fig. 2 is afront view; Fig. 3 is a top view; Fig. i is a top view, in which theprojection (0;) is lengthened.

To enable others skilled in the art to make and use our invention, wewill proceed to describe its construction and mode of operation.

The drawings are on a scale of about twothirds of an inch to an inch inthe working coupling.

A is a cast-iron box, the front of which is left open to receive the endof the pole of the car or carriage; it is cast with the top open so thatthe uncoupling rod (C) may be connected with the tumbler B in arrangingthese parts in the box: it is covered with a lid of sheet-iron, througha small hole in which, the uncoupling rod projects. The lid protects theinside of the box from dirt and moisture. The box has a projection, a,with an eye, 6, through which the coupling is firmly fastened to the caror carriage by means of a bolt upon which the coupling freely turns.

B is a tumbler or latch of cast-iron, working loosely on the strongbolt, 0, which passes through holes in the sides of the box. It isrounded at the end where it comes in contact with the beveled face ofthe enlargement (d) of the pole, to facilitate the oper ation ofuncoupling.

C is the uncoupling rod; it is connected to the tumbler by a pivot orhook.

D is a part of the pole of a car or carriage having at the end anenlargement, cl, the face of which forms a bevel angle with the pole, asshown in the drawings.

E, is an adjustable rest; it may be raised or lowered by thethumb-screw, F, for the purpose of keeping the pole at any desiredelevation. F screws through the bottom of the box and is fastened to therest, E, by anotfhg r small screw, G, Working into the end 0 To give thecoupling increased support, when an unusually heavy pole is intended tobe used the projection, a, may be lengthened, as shown in Fig. 4, sothat its end may slide upon a flat bar of iron secured to the under sideof the frame of the car.

The projection, a, may be made separately of wrought iron, with arms toclasp the sides of the box to which said arms may be fastened in anysubstantial manner.

The operation of coupling is effected, by pressing the pole into thebox. The pole is uncoupled and may be removed without obstruction, whenthe tumbler is drawn up above the enlargement, d.

I/Vhat we claim and desire to secure by Letters Patent, is

1. Constructing the enlargement (cl) of the pole, with a beveled face inthe manner and for the purpose substantially as set forth.

2. Giving the tumbler, B, a rounded form at the end in the manner andfor the purpose substantially as set forth.

3. The extension (at) having an eye (6) for joining the box to the car.
